Calculation of Grinding Balls Surface Area and Volume

2018-10-8  Earlier, we have mentioned one of the grinding media characteristics which is defined by the ratio of the surface area to the volume of the grinding ball (link to the article). As smaller the ratio value,as thinner (the better) grinding process will be. We hope this information will save your time for searching a seemingly simple formula.
